The following is the steps I used to install CentOS 7 on my Lenovo laptop.

When closing the lid of your laptop, your computer suspends in order to save power. You can prevent the computer from suspending when closing the lid by changing the setting for that behavior.Warning: Some laptops can overheat if they are left running with the lid closed, especially if they are in a confined place like a backpack. Therefore, consider if changing the default setting (suspend) is the best option in your case.
Open the
/etc/systemd/logind.conf
file for editing.
Find theHandleLidSwitch=suspend
line in the file. If it is quoted out with the#
character at the start, unquote it.
If the line is not present in the file, add it.
Replace the defaultsuspend
parameter with
lock
for the screen to lock;
ignore
for nothing to happen;
poweroff
for the computer to switch off.
For example:
[Login] HandleLidSwitch=
HandleLidSwitch=lock
Save your changes and close the editor.
Run the following command so that your changes preserve the next restart of the system:
# systemctl restart systemd-logind.service
Warning: Keep in mind that restarting the service forcibly interrupts any currently running GNOME session of any desktop user who is logged in. This can result in users losing unsaved data.

file, see thelogind.conf(5)
